Uhm... on which browser are you playing?
This might actually be an issue with the old web build — the .zip file I uploaded (quite possibly a couple of years ago) could be slightly corrupted. It just went unnoticed until now thanks to how differently browsers handle web builds.
In which case you should probably see this:
- works fine on Chrome- throws an "input stream error" at the loading/unpacking stages (and possibly an "infinite loop error" should it go past that) on Firefox
- behaves erratically on Edge/Safari
That said... I’m preparing a fully rebuilt web version right now — it’ll be up in about a week. Thanks for catching this btw - another thing I'll be on the lookout for!
